The EPA and Colorado’s Department of Public Health and Environment require every person on the CU-Boulder campus to make sure pollutants do not enter sanitary drains or storm drains.

Contact Environmental Health & Safety at 303-492-6025 or email ehs@colorado.edu for advice about how to properly dispose of materials so they don’t end up in our waterways.
